Apache

前面谈到 Samba 服务器的 MySQL 用户认证,实际上我老早就写过 Apache 针对 MySQL 的认证。不过以前只是测试而已,没有实际使用。前文提到知识管理,实际上在公司内部我们运行着一个基于 pLog 的博客系统。原先的系统没有发布到互联网,后来为了能让公司异地的各分支机构也能使用该博客系统,所以,决定发布到互联网。为了最小程度的降低对博客系统的 Hack ,所以我决定采用外挂的 mod_auth_mysql 模块来实现用户认证,从而降低公司内部系统暴露给非授权用户的风险。

  在这次安装中,才发现原来 mod_auth_mysql 有好几种版本,而且文档几乎都是残缺不全的。本文下载的程序来自 sourceforge.net (sf.net)

  http://modauthmysql.sourceforge.net/

  目前的版本为 2.9.0 ,下载后,建立目录 mod_auth_mysql ,然后进入该目录解压。(不要直接在 /usr/local/src 下解压) ,根据 BUILD 文件的指示,安装步骤如下:

apxs -c -lmysqlclient -lm -lz mod_auth_mysql.c
apxs -i mod_auth_mysql.la

  然后把下面这行加入 httpd.conf

  LoadModule mysql_auth_module modules/mod_auth_mysql.so

  实际上编译和安装并不困难,配置才是比较大的挑战,特别是要已经现有的用户表结合起来。我的 plog 数据库的用户表是 plog_users ,我设置的配置如下:

  

  

  AuthType Basic

  # 连接数据库的主机地址,一般用本地连接,所以为 localhost

  AuthMySQLHost localhost

  AuthMySQLPort nnnn

  # 数据库的名字

  AuthMySQLDB plog

  # 连接数据库的用户?

  AuthMySQLUser plogdb_user

  # 连接数据库的口令

AuthMySQLPassword password
# none: not encrypted (plain text)
# crypt: UNIX crypt() encryption
# scrambled: MySQL PASSWORD encryption
# md5: MD5 hashing
# aes: Advanced Encryption Standard (AES) encryption
# sha1: Secure Hash Algorihm (SHA1)`
AuthMySQLPwEncryption md5
AuthMySQLEnable On
AuthMySQLUserTable plog_users
AuthMySQLNameField user
AuthMySQLPasswordField password
AuthMySQLGroupTable plog_users
AuthMySQLGroupField user_group

  从以上配置可以知道,这个模块实际上对用户表没有特别的要求,只要能找到 用户名和对应的口令即可,如果需要对一个组作验证,那么需要 group 那个列。

  由于公司内部所有的用户都具有相同的组,所以,在验证时一般采用组用户来验证,因此要在 plog_user 表添加列: user_group ,并把所有行的 user_group 列 update 为某固定值,例如 mygroup 。

  在这里 groupTable 和 UserTable 是同一张表,如果需要一个用户属于多个 group ,那么必须另外建立 group 表。

  做好以上工作后,在需要加密的目录添加 .htaccess 文件如下:

  Authname "请用管理博客的口令和密码登陆"

  Authtype Basic

  Require group mygroup

  这样一个外挂的验证系统部署完毕,这种部署对于电子商务应用中,多个不同应用的用户表整合具有很好的效果。修改的代码不多。

  修改用户口令可以用 PHP 的

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
